Patent EP-0035388-A3 (EP)
Title: Pipe connector
IPC: F16B7/04
Filed: 1981-02-27
Abstract: A pipe connector for connection to a pipe having a plain end comprises a body (10) having a profile matching that of the pipe, and a pair of jaws (12) extending outwardly for insertion within the end of the pipe. The jaws are formed with oppositely directed clamping surfaces (24, 26) for engaging the inner wall surface of the pipe end. One of the jaws (14) is fixed and integral with the body (10). The other jaw (16) is pivotally mounted on the fixed jaw (14) and is extended inwardly of the body (10) where it is threadedly engaged by a screw (38) which connects the pivoted jaw with the body so that by rotating the screw (38) in the appropriate direction the pivoted jaw (16) pivots away from or towards the fixed jaw (14) to clamp or unclamp the jaws from the pipe. The screw (38) thus provides a positive clamping force which greatly assists the dismantling of the connector from a pipe end when desired. The screw (38) also retains the pivoted jaw (14) in place and there are no loose parts to become lost.

Title: Character seize reduction and shift in a matrix printer, and method
IPC: B41J2/23
Filed: 1984-11-08
Abstract: A matrix printer normally cooperates with a particular character generator by means of which coded information representing characters to be printed is translated into a matrix of print commands for print styli printing dots out of which a character is composed. In accordance with the invention, the same character generator is used for printing smaller characters in superscript, subscript or in formal footnotes, by using a particular algorithm to translate the generator information into different set of information for each character, so as to reassign print commands for the several print styli.
Patent EP-0151953-A3 (EP)
Title: Topical drug release system
IPC: A61K9/06
Filed: 1985-01-17
Abstract: A pharmaceutical composition for topical administration consisting of two liquid phases designed to be admixed in situ or prior to use. The first phase contains a dissolved drug, and is preferably saturated in the drug, whilst the second phase is a chemically or physically different liquid from that in the first phase and contains no drug, but is miscible with the first phase. The two liquids are selected so that, on admixture of suitable volumes of the phases, the resultant drug concentration exceeds the saturated drug solubility in the resultant mixture. This produces a liquid mixture supersaturated in drug, which has been found to increase the rate of drug penetration into the skin. The two liquid phases may be gels, and the drug may be hydrocortisone.

Title: Bolster suspension for a railway vehicle bogie
IPC: B61F5/06
Filed: 1986-11-26
Abstract: A secondary suspension for a rail vehicle truck is arranged between a suspension support connected to the car body of the vehicle and a spring support. It comprises several spring groups, whose spring elements each have a set of coil springs held by an upper and a lower spring plate and a metal-rubber spring element and are individually interchangeable. The spring elements are designed so that replacement of the spring groups can be carried out with the truck installed on the vehicle and without using a pressure stand or a lift. This goal is achieved by the fact that there are at least two diametrically opposed holder claws for spring tension holders on the upper and the lower spring plate of the spring groups, to which the spring tension holders are attached when the spring elements are compressed.

Filed: 1986-09-30
Abstract: A telephone instrument has a housing constructed from a first 
section (1) and a second section (2), the first (1) and second (2) 
section being connected together to form a housing. The second 
section (2) comprises three identical first sub-sections (4,5,6) 
which are substantially rectangular in plan. The number of first 
sub-sections is dependent on the dimensions of the first section 
(1) which is formed in one piece. The first sub-sections (4,5,6) 
comprise a first part defining a regular array of apertures (22, 
Figure 2) suitable for locating an array of pushbuttons (8). The 
array of apertures (22) extends across the full width of the

a continuous regular array of apertures extends across the 
arrangement of first sub-sections. A cover plate (9) covers 
locations in which no pushbutton is provided, the cover plate being 
located by the apertures (22).  
     The first sub-sections also comprise a second part defining a

Patent EP-0215669-A3 (EP)
IPC: G01N33/543
Filed: 1986-09-16
Abstract: An analytical device and a method for the analysis of 
biochemicals, microbes and cells using a piezoelectic crystal 
biosensor, utilises the resonant frequency change caused by 
weight change on the surface of the piezoelectric crystal on 
which receptor materials is immobilised.  
     Four piezoelectric crystals 161 are mounted in a common 
cell 164. Each crystal 161 has a pair of electrodes 162 connected 
by leads 163 to an oscillator circuit 166. The electrodes 162 
of three of the crystals 161 are treated to deposit different 
lectins thereon and those of the fourth left untreated as a 
reference. A peristaltic pump 169 draws liquid through pipes 
165 and cell 164 from a valve 1610 which is solenoid operated 
to draw from a blood sample supply 1612 or from another valve 1611 
drawing from either a phosphate buffer solution reservoir 1613 
or a removal agent reservoir 1614. The circuit 166 is connected 
to a frequency counter 167 whose outputs are fed to a computer 
168 which controls the pump 169 and valves 1610 and 1611.  
     The crystals 161 are first resonated to establish their 
resonant frequencies. A blood sample is then drawn through 
the cell 164 by pump 169. Type A erythrocytes are attracted 
to one of the lectins, types A and B to another, and type O 
to the third. Phosphate buffer is then drawn through by adjustment 
of valves 1610 and 1611. Resonant frequencies are measured 
again and compared with those originally obtained. From the 
changes observed, determination of type is made by the computer. 
Removal agent is then drawn through to remove remaining erythrocytes 
and phosphate buffer drawn through to prepare for further samples.
